bff8f2543b units: set LockPersonality= for all our long-running services (#6819)
Let's lock things down. Also, using it is the only way how to properly
test this to the fullest extent.

924453c225 units: lock down coredump service a bit
Dissecting a coredump is possibly risky and might take a while, hence
lock down the unit as much as we can.

3c171f0b1e coredump: rework coredumping logic
This reworks the coredumping logic so that the coredump handler invoked from the kernel only collects runtime data
about the crashed process, and then submits it for processing to a socket-activate coredump service, which extracts a
stacktrace and writes the coredump to disk.

This has a number of benefits: the disk IO and stack trace generation may take a substantial amount of resources, and
hence should better be managed by PID 1, so that resource management applies. This patch uses RuntimeMaxSec=, Nice=, OOMScoreAdjust=
and various sandboxing settings to ensure that the coredump handler doesn't take away unbounded resources from normally
priorized processes.

This logic is also nice since this makes sure the coredump processing and storage is delayed correctly until
/var/systemd/coredump is mounted and writable.

Fixes: #2286
